-To all whom 'it may concern:

Be it known that I, FREDnIuo B. CAMORS, citizen of the United States,residing at New Orleans, in the parish of Orleans and State ofLouisiana, have invented new and useful Improvements in Methods ofRemoving Incrustations from Water-Containers, of which the v .followingis a specification.

My invention pertains to methods of removing incrustations from steamgenerators and other Water containers; and it consists in theinexpensive method, hereinafter derious scribed and claimed, by thepractice of which incrustations may he expeditiously and thor oughlremoved from water containers of valzinds such as steam boilers, tanks,condensers, and steam and other heaters and the pipes and connectionsthereofv In carrying out my method I introduce into the container to becleared of incruster tions a solution of pure or diluted hydrochloricacid and a solution of either sodium Y [bisulfate or sodium aluminate.

Experiment has demonstrated the fact that excellent results may heobtained by using a diluted solution of hydrochloric acid at Baum and asolution of 8 Baum of sodium bisulfate, in the proportion of two thirdsof the former in volume to one-third of the latter; These are introduced.into the water container in quantities sufiicient to efi'ect theremoval of the incrustations. Complete results may also he obtainedunder certain conditions by using a solution of hydrochloric acid at 4Baum combined with 3% of a solution of sodium aluminate at 10Specification of Letters Patent. 4 Application filed February 13, 1908..Serial No; 415,710.

stituents being also introduced into the container to be cleared insufficient quantities to effect the removal of the in'cr'ustations'.

The constituents may when deemed expedient be heated precedent to theirintroduction into the container, this with a View of effecting theremoval of the incrustations more uickly than could be done by the useof. cold ingredients. Or in the discretion of heating of theconstituents may be effected the container.

Having described my invention, what I ent, is: J I
